弹齿对辊式玉米根茬收获机的设计与试验

Search and Test Spring Finger Contra-rotating Cylinder Corn Stubble Collector

玉米根茬是一种极具开发性的清洁生物质燃料,为充分利用玉米根茬,研制了一种玉米根茬收获机。其采用偏置式铲刀、弹齿对辊式根茬捡拾与根土分离机构,一次性完成玉米根茬的挖掘、捡拾、脱土等收获环节。为此,以玉米根茬挖掘率和脱土率为性能指标进行田间试验。试验表明,研制的玉米根茬挖掘收获机性能满足使用要求,解决了人工挖掘劳动量大了田间焚烧造成土壤板结和环境污染等问题,为我国生物质资源利用的农业装备制造业提供了技术装备支撑。

Corn stubble is a kind of clean fuel,in order to make full use of it.a corn stubble harvester was developed.Using offset type shovel、spring finger contra-rotating type picking up and the root soil separation mechanism can be one-time complete root crop of digging,picking-up,putting off soil.Corn stubble digging and separating rate as indexes for field test.Experiments show that：the design of a spring finger contra-rotating type corn stubble harvester can meet operating requirements.It can solve the artificial digging large amount of labor,burning problem caused by compaction in soil,environmental pollution,and provide help on utilization of biomass resources in agricultural equipment.
